On long time dynamic and singularity formation of NLS
… mass critical nonlinear Schrödinger equation (NLS). We will focus on the singularity formation and long time asymptotics. To be specific, there are two parts in the thesis. In the first part, we give a construction of log-log blow up solutions which blow up at m prescribed points …

Existence and Stability of Solitary Waves for NLS with Defects
… that the soliton profiles for the concentrated NLS are in fact exact minimizers of the Sobolev embedding $H^s(\rn)\hookrightarrow L^\infty(\rn)$, which provides an alternative calculation and justification of the sharp constants in these inequalities. Lastly, we consider the degenerate …

Charakterisierung des Kerntransportsystems von Linker-Histonen
… Es wurden mehrere Kernlokalisierungssignale (NLS) in H1-Histonen identifiziert. H1 enthält wenigstens zwei verschiedene Typen von NLS, die sich beide von dem klassischen NLS-Typ unterscheiden. Der NLS-Typ 1 entspricht der wenig strukturierten, hoch-basischen C-terminalen Domäne. Der NLS-Typ 2 …

The nonlinear Schroedinger limit of the complex Ginzburg-Landau equation.
… of the nonlinear Schrodinger equation (NLS) in one dimension under periodic boundary conditions. Using an averaging technique which is similar to a Melnikov method for pde's, necessary conditions are derived for the persistence of NLS solutions under the CGL perturbation. For the …

Structural and Biochmical Studies of Nuclear Import Factor Karyopherin Beta-2
… nuclear localization and export signals (NLS/NES) and mediate the transport of macromolecules across the nuclear envelope, a process regulated by Ran GTPase through its nucleotide cycle. Diversity and few number of available signal sequences recognized by Kapbeta s have prevented …

Neurologin Function in Excitatory and Inhibitory Synapses
Neuroligins (NLs) are postsynaptic cell adhesion molecules which by binding to presynaptic neurexins (NRXs) are thought to mediate synapse formation and function. Both NLs and NRXs are discussed in the genetic correlation to Autism. Over-expression of NLs could induce the formation of synaptic …

The functional motifs for nucleocytoplasmic shuttling of C-terminal fragment of c-Met : A novel "pH-dependent' nuclear localization signal
… nor the responsible nuclear localization signal (NLS) has not been previously reported. Here, we report that two histidine residues separated by a 10-amino-acid spacer (H1068-H1079) located in the juxtamembrane region of c-Met function as a putative novel NLS. Immunocytochemistry and cellular …

Determinants of Choice of College Major Among Women and Men: Comparisons of Cohorts in the Late 1960s and 1970s (Sex Differences)
… from three of the National Longitudinal Surveys (NLS) of Labor Market Experience: (1) the NLS of Youth ages 14 to 21 in 1979; (2) the NLS of Young Women ages 14 to 24 in 1968; and (3) the NLS of Young Men ages 14 to 24 in 1966. College major is specified as a function of aspirations for market …

A visual ethnographic study on nurse lecturers’ enactment of compassionate care within the adult pre-registration nursing curriculum
… nursing curriculum (APNC) by Nurse lecturers (NLs). Background: Compassionate care is rooted in the nursing profession and there is a general assumption that nurses are compassionate to those they serve. There has been much debate on whether compassionate care can be taught or is it innate to …

Lagrangian modelling of nonlinear waves in optical fibres
The Lagrangian perturbation method for the NLS is revisited in the form of an equivalent direct problem. The analogy can be extended to arbitrarily perturbed systems. It is then possible to provide first order perturbation expansions for the fundamental soliton. The case of the damped NLS is …

Evaluating the Utility of an Atmospheric Pressure Chemical Ionization Mass Spectrometer for Detecting Organic Peroxides During Beta-Pinene Ozonolysis Experiments
… was based on utilizing the neutral-loss scan (NLS) analysis mode of the APCI-MS/MS to observe ion signals exhibiting unique mass losses of 34 u. This mass loss was considered exclusive to protonated organic peroxides containing a hydroperoxy moiety. Given this observation, the NLS analysis mode …

Justification of a nonlinear Schrödinger model for polymers
<p>A model with nonlinear Schrödinger (NLS) equation used for describing pulse propagations in photopolymers is considered. We focus on a case in which change of refractive index is proportional to the square of amplitude of the electric field and consider 2-dimensional spatial domain. After formal …
